Answer 1

Hello, Buddy!!

ɢɪᴠᴇɴ:-

• In ∆ABC
• Point A → (10,4)
• Point B → (8,1)
• Point C → (3,5)

ᴛᴏ ꜰɪɴᴅ:-

• Area of Traingle.

ʀᴇQᴜɪʀᴇᴅ ꜱᴏʟᴜᴛɪᴏɴ:-

• Area of ∆le = |x1(y2-y3)+x2(y3-y1)+x3(y1-y2)| sq.units

→ |10(1-5)+8(5-4)+3(4-1)|

→ |10(-4)+8(1)+3(3)|

→ |-40+8+9|

→ |-40+17|

→ |-23|

→ 1/2×23

→ 11.5

• Area of ∆ABC ☞ 11.5 sq.units.
